Passive Intraoperative Language Mapping Using Electrocorticographic Signals

Intraoperative brain mapping is an important step in performing neurosurgery because it allows to spare the eloquent areas of the brain and increase the post-operative life quality for patients. However, the gold standard - electrical cortical stimulation - leads to seizures in up to 30% cases when language cortex is mapped intraoperatively in epilepsy patients. Modern neurosurgery is facing the need for a more innocuous method to intraoperatively map functionally critical cortical zones.
